- Application filed February My invention in its broadest aspect relates to the product-ion of printingdace equipped bodies 111 general, but more particularly to so-calle d line-cast slugs each comprising a shank portion wh1ch,"1n accordance with common practice, is cast in a mold provided as one member, and a head-portion, either continuous or interrupted, andpre'senting a puntmgdace portion or portions comprising such printing characters asletters, nu

merals and rule iiorm elements, and, according to common practice, cast integral with the shank portion and into matrices provided as members separated from the shankmold member and positioned in alignment with each other at the open side of the mold cavity out the shank-mold'member.

My invention further relates to the aligning, either crosswiseorilengthwise of the printing-face-equipped bodies, of the prlnt- 'ing faces of such bodies when grouped together to present the printing form; and more especially, to-the' alignment of such faces in a direction crosswise of such bodies,

as, 1 01" example, in the case of printing bodies for printingblank forms andoffice and factory forms comprising parallel rule lines extending in one direction only, or intersecting parallel rule llnes, and in the case of tabular work comprising lines, or columns, of single letters, words or numerals, in all of which cases the accurate alignment of the printing faces of adjacent printing bodies'is necessary to produce high grade work. a I

Asprinting-face bodieshave been provided hitherto, non-alignmentof the printtaces-thereon, when such bodies are grouped togetherto comprise the form,

has been practically inevitable, and this especially the case with the above-referredto line-cast slugs which, n the mak ng up of a printing form, aregrouped together,

in fiatwise relation, in a frame, and where failure to accurately align the ends of the slugs, as, for example, through carelessness or lack of skill, occurs, theprinting faces on adjacent slugs are out of alignment, with the above-referred-to disadvantage. Furthermore, the head portions of line-cast slugs,

as co'mmonly manufactured, are sometimes ofl'set relative to the shank portlons thereof,

in a directionlengthwise of the islug, 'due to hon-alignment of the shank moldcavity and the matrices, and. when; this occurs either '16, 1924. seriainmeeazss.

printing faces on adjacent slugs.

My primary ob ect is to overcome the obections above referred to, to the end that alignment otthe printmg faces on adjacent printing bodies, especially in the case of line-cast slugs, will be insured, and without requiring skill or apainstaklng operation and regardless of the non-alignment of the head jortions of the slu s relative to the shank portions thereof. s

I have chosen to llustrate my invention in connect on With the producing of line-cast slugs for-the composing, of forms from which blanks having intersectlng rule lines are to be printed, and alsoin connection with line-cast slugs for the composing of forms from which blanks having rule lines fiextondmg in Ol16-d1f8ClZlOlLOI1ly are to be printed, but without intending to limitmy inventionthereto. A

Referring to'the accompanying drawings, wherein Figures 1 to 9, inclusive, relate to the forming of a line-cast slug the head portion of which is continuous, and Figures 10 and 11 to a slug the head portion of which is interrupted Figure l is a perspective view of a moldmember in which the shank portion of the line-cast slug is formed, and a matrix-composing stick containing a series of matrices in which the headportion of the slug is cast, the shank and headformingportions referred to bein shown in separated conditlOlL Figure 2 is a section takenthrough the assembled members of F 1g. 1, these two views be ng somewhatdiagrammatic,' 'ith certain parts of the structure with which they; are associated in common practice, omitted, sufficient only of the structure being shown to illustrate the application of my invention. 1 Figures 3, 4 and 5 are perspective views, Figs. 4 and 5 being broken views,

representing different kinds of matrices which are employed inthe casting of the 1 slugs for producing the printed ruled blanks, composed of ntersecting ruleline s,' above ref red to: Figure 6'isa lans-view of a plurality of the slugs produced the struc ture of the preceding figures, these slugs being grouped together into the relative positions occupied by them in the composing of the printing form. Figure 7 is a view in side elevation of the upper portion of one of the similar slugs of Fig. 6. Figure 8 is a perspective view of the grouped slugs of Fig. 6. view of the central upper portion of any one of the slugs above referred to, the slug being viewed from the side opposite to that shown in Fig. 7. Figure 10 is a plan view of a printing-face-equipped slug in accordance with my invention, to be grouped with similar slugs for the printing of blanks composed of rule-lines extending in the same direction, the slug shown being of a type wherein the portions thereof presenting the printing faces, and comprising the interrupted head of the slug, are wider than the shank-portion of the slug; and Figure 11, a perspective view, with a portion partly broken away, of a pair of the'slugs of Fig. 10 in assembled position with-a filler-slug interposed therebetween.

As a preface to the following description it may be stated that, as machines are commonly provided for producing line-cast slugs theshank-mold portion and the matrices are separate, the shank mold portion being provided on the machine and associatedwith means for discharging into its mold cavity and into, and against, the matrices, molten metal to form the'slug, and

the matrices being grouped together in a matri:;con'iposing stick adapted to be positioned on the machine to close the side of the shank-mold and present the mold cavities in the matrices to the metal introduced into the shank mold. Machines of this type being well-known in the art, detailed showing thereof is omitted, only such portions of the machine as are necessary to an understanding of my invention being illustrated. Accordingly a shank-mold member is illustrated somewhat diagrammatically, however, at 10, the mold cavity therein and in which the shank portion of the slug is cast, being shown at 11. This mold cavity opens through the upper surface of the member 10 and receives through its ported undersurface, represented at 12, the molten slug metal from which the shank and head of the slug are to be formed. A matrix-composing stick is represented at 13, the central opening 14: therein receiving the matrices, represented at 15 shown as formed of the body portions 16, which extend into the opening 14, and the lugs 17 which seat upon the upper surface of the stick 13, the matrices 15, assembled with the stick 13, being held in place therein by a clamping, follower, block 18 cooperating with a clamping screw 19 havingthreaded engagement with an end portion of the stick 13.

Figure 9 is a broken, perspective,

The matrices 15 are provided with mold cavities of a contour. or contours, as the case may be, for producing the desired printing face on the line-cast slug to be produced. The particular form of slug shown in Figs. 1 to 9 inclusive at 20 and embodying my invention, is provided for producing blank ruled forms comprising intersecting rule lines. the rule faces on the slugs for printing the horizontal and vertical rule lines being represented at 21 and 22, respectively, these rule faces being provideo on, and as a part of, the head portions 23 of the slugs. the shank port-ions of which are represented at 2 1-. Three kinds of matrices. shown in Figs. 3. 4 and 5. are employed in the producing of the slugs 20. The matrices of the form shown in Figs. 3 and 4 are provided for producing portions of the single horizontal rule faces 21 which extend lengthwise of the slug, and the matrices of the form shown in Fig. are provided for producing the remaining portions of the single rule faces 21 and also the rule faces 22 intersecting therewith. these last-referred -to rule faces being the ones whiehitis desired be accurately alined in the composing of the printing form from a plurality of the slugs.

In accordance with my invention the line cast slugs are provided with means, prefci ably of an interlocking character, for insuring such relative positioning of the slugs in grouped relation, that accurate alignment: of the printing-faces thereon in a direction crosswise of the slugs will be insured. Referring to Figs. 6 to 9 inclusive the particular illustrated form of such means is of: the lug and socket type, each line-cast slug hein provided with a lug. represented at 25.. extending from one face thereof. and with a boss 26 containing a laterally-opening socket 27, these lugs and sockets being located exactly in the same position lengthwise and crosswise of the slug. In the Jarticular construction shown the positioning means referred to are, provided above the shank portion of the slug on the head portion thereof. these parts being preferably formed by casting the metal forming the head portion into matrices of such contour as to produce the lugs and socketed bosses referred to, To

this end the mold cavit} of the matrix of Fig. 3 is so shaped as not only to produce the ruleface 21, as above described, but also toproduce the lugs and socketed boss, the portions of the mold cavity by which the lug and boss are produced being indicated at 28 and 29.; p

In the composingrofa printing form f om the line-cast slugs shown, the slugs are grouped together,, or assembled, as representedin Figs. 6 and ,8, in which position the lugs extend into, and closely fit. the

sockets 27 of adjacent slugs. as the lugs and sockets occupy the same position on each slug, relative to the rule faces 22, the positioning of the slugs as stated insures/accurate alignment of these rule faces to pro-,

duce perfectly straight, unbroken, rule faces in the prlnting form, and it is thus immaterlal, so far as the align ng of the rule faces is concerned whether or not the headportions of the slngs accurately align with the shank portions thereof. lneffectth'eside walls of the sockets '27 and, the surfaces of the lugs co-operating therewith, as above stated, form cooperating stop surfaces by which the slugs in. the operatioirof assem portion of the slug'maybe, and as shown is, interrupted, with the printing faces extending laterally beyond the face of the shank, the shank-portion of the slug is represented at 28 and the printing face portions at 29, the portions 29 with the interlocking means hereinafter referred to, forming the laterally beyond the opposite facesfiof the shank 28, as shown. The interlocking devices for the slugs, shown as comprising the lug and sooketportions 30 and-31, as explained of the structure of the preceding figures, are of such form that the lug 30 extends outwardly beyond theadjacent ends of the printing face portions, 29 and the socket ofthe portion, 31 vextends inwardly relative to the other ends of theportions2 9,

as Shown, whereby when a plurality of the, slugs 28 are grouped together as shown in Fig. 11, the lugs 30 will enter the sockets 31 of adjacent slugs 28 and interlock the slugs a explained of the other structure. I

In the aroducing of the slug now being described, the same general character of devices may be used, and the same operations may be practiced, as explained of the structure of the preceding figures. In thiscase the mold cavities instead of being'relatively narrow, would be relativelywide and extend beyond the side of the shank-mold cavity,

blank matrices would be interposed between the printing-face-forming matrices to form the interruptions in the head portion of the slug and the lug and socket-forming matrices would be without printing-face-forming mold cavities: however, the lug and socket formingmold cavities being grouped in a mold member with the matrices forming the printing-face portions of the slugs, the lugs lb Letters Patent is? head of the slug,'andextend1ng equlcllstanfl time y v and sockets 30 and 31 bear a fixed relation tothe printing faces of the slug as they do in the case of the slug of thepreceding figures, wherein the head'is continuous, wherecaused to accurately ali'ne, I I

Where the slugs are formed with the overhanging, or laterally projecting, head portion 29, as explained, and it will beunderstood that this feature'maybe incorporated in a slug ofthe continuous-head type, if desired, filler, blank, slugs, asfor example of the form represented at and shown as un provided with heads, would, be interposed between adjacent ones of the slugs 28' to fill the space therebetween, while permitting endwise abutting of alined 'printing face portions. L

VVhile I have illustrated and described my invention as applied to the production of certain forms of printing-face-et1uipped bodies, I do not wish to be understoodas intending to limit it thereto nor to the particular printing-faces shown,as the invention may be employed in the production of various other forms of printingifaceequipped bodies and various other printingfaces where it if; desired that alignment of printing-faces on adjacent printing-faceequipped bodies be effected.
